Let me second Tom's endorsement of the Wall Street Journal piece on the CIA. It is quite powerful. Here is an excerpt:

The CIA, either purposely or with gross negligence, made a series of decisions that led to Ms. Plame becoming a household name.

First: The CIA sent her husband, former Ambassador Joseph Wilson, to Niger on a sensitive mission regarding WMD. He was to determine whether Iraq had attempted to purchase yellowcake, an essential ingredient for nonconventional weapons. However, it was Ms. Plame, not Mr. Wilson, who was the WMD expert. Moreover, Mr. Wilson had no intelligence background, was never a senior person in Niger when he was in the State Department, and was opposed to the administration's Iraq policy. The assignment was given, according to the Senate Intelligence Committee, at Ms. Plame's suggestion.

• Second: Mr. Wilson was not required to sign a confidentiality agreement, a mandatory act for the rest of us who either carry out any similar CIA assignment or who represent CIA clients.

• Fourth: Although Mr. Wilson did not have to write even one word for the agency that sent him on the mission at taxpayer's expense, over a year later he was permitted to tell all about this sensitive assignment in the New York Times. For the rest of us, writing about such an assignment would mean we'd have to bring our proposed op-ed before the CIA's Prepublication Review Board and spend countless hours arguing over every word to be published. Congressional oversight committees should want to know who at the CIA permitted the publication of the article, which, it has been reported, did not jibe with the thrust of Mr. Wilson's oral briefing. For starters, if the piece had been properly vetted at the CIA, someone should have known that the agency never briefed the vice president on the trip, as claimed by Mr. Wilson in his op-ed.
